I'm a college senior who is graduating in a couple weeks so for the past few months I've been job searching like crazy trying to get a job lined up for after graduation. I currently have a "job offer" with a relatively small company; I'm working part-time for them for training purposes and will get fully hired a month after graduation. (I should note that I really only went with them as a "back up" of sorts) However, I have an interview next week with another, much larger company that I have been wanting to work for since my freshman year and I feel that it is very likely that I will get an offer from them (fingers crossed).
I'm having very conflicted feelings about my situation because if I do get an offer with the second company, I will most likely go with them over the small company. However, I've been talking with the smaller company for almost 3 months now and they have done a lot/are planning to do a lot for me i.e. gave me a laptop, work bag, company shirt, an office, planning to fly me over to Canada for training, planning a company boat cruise to meet the other employees, etc. So if I do end up not working for them, I'm going to have to awkwardly give all this stuff back.
I guess I'm just afraid that I will be unethical/seem two-faced to them because prior to my first interview with the second company, I've been saying to them how "excited" I am to work for them and I want to stick with one company, but if I go with the other company then it'll seem like I didn't want to work with them when in reality the other company is my "dream" company and offers better benefits.
I haven't let the small company know that I'm interviewing with the second company, and if I continue this, get a offer, and then let the small company know I don't want to work for them, I'm afraid the news will come off like a slap to the face. I'm meeting them next week (on the same day as my interview no less) so I'm wondering if I should at least let them know if I'm interviewing with another company? Or is that none of their business? What is the best thing I should do in this situation?
